Determine what applications can be safely moved to the cloud and which ones cannot. Consider issues of sensitivity where it may deemed too risky to store information in the cloud, such as credit card data. This decision will obviously differ by organization — an auction-type payment provider will certainly utilize the cloud, while a large B2B bank will most likely not risk the potential exposure of its customer account data. Also, consider issues associated with latency constraints which would deeply impact applications such as algorithmic trading. Many of these applications are “co-located” in the stock exchange in order to circumvent the lag of any external network. However, there are many applications where latency in the low seconds is acceptable, and these may be good candidates for cloud residency.

Cloud-washing, a practice of renaming or repackaging existing products and dubbing them cloud-ready, has become an art form. Every software package, service and now even hardware is described as cloud-enabled. Seemingly, we are all headed into the clouds never to return. Sounds like heaven, right? Maybe, maybe not.

While the atmosphere is everywhere, the cloud decidedly is not. It is by definition remote. That means if your applications require the highest in performance, cloud may not be the answer. For example, when you rent movies that are delivered over the cloud in real-time to your home, periodically, everything freezes and you see the infamous “buffering” message. While this may enhance the mystery of what is going on in the “Lost” episode you’re watching, it would be a disaster for algorithmic trading. In that environment milliseconds can determine profitability or loss.

Not all applications can be completely move to the cloud. In some cases this is done by design and the type of application, while in others the impact of migration is too high. For those business-critical applications that require the highest performance and have the most sensitive information and complexity of process, a hybrid model of cloud services to bridge the datacenter, branch offices and trading partners is best.

In this slideshow, Charley Rich, vice president of product management and marketing at Nastel Technologies, covers the top five best practices for ensuring optimal performance and uptime when using the cloud for your most demanding applications.
